Abstracts

EN

The paper presents the problems encountered during calibration of devices equipped with all-weather microphones, which results in frequent omissions in the periodic check-up of monitoring systems. Such a check-up should be regularly carried out, as it would result in broadening and unification of the knowledge concerning the measurements and the evaluation of their uncertainty in the environmental conditions.
